IvoP Posted January 20, 2012 Share Posted January 20, 2012 I created layout for my system and I have 6 locos with 24 points. I was thinking of using one booster for locos and connect all R8247 decoders on separate (isolated track) booster(s). I cannot find anywhere how much current does one point motor need.I would like to know how many boosters I need for 24 point motors and how much point motors can be run at the same time. I suppose that one booster is not enough... Link to comment Share on other sites More sharing options...
David55 Posted January 20, 2012 Share Posted January 20, 2012 Hi IvoPI have 27 sets of points on my track, the first decoder is fed from the track and then each is wired in tandem.I don't have any boosters.After the decoder has fired a point, you need to wait a few seconds to fire a second point wired to the same decoder.You can fire a point on each decoder at the same time, then these need to recharge.Hope this helpsDavid Link to comment Share on other sites More sharing options...
IvoP Posted January 20, 2012 Author Share Posted January 20, 2012 And if I can only operate one motor at the time, how much time needs to pass between two motor actions? Is 0.2-0.5 seconds enough?Thanks in advance! Link to comment Share on other sites More sharing options...
IvoP Posted January 20, 2012 Author Share Posted January 20, 2012 Thanks for reply! I'm newbie here... Can you tell me what does it mean 'wired in tandem'? So actually you have only elite for power supply? So one decoder can be used only once in few seconds... that sucks for me cause i was planning to build control system that could change points quickly...

stevecamden Posted January 20, 2012 Share Posted January 20, 2012 The R8247 decoder will throw three points at the same time with ease. You then need a couple of second recharge. If you have 2 decoders and the points wired up appropriately then you should be easily able to achieve all that you need Link to comment Share on other sites More sharing options...
IvoP Posted January 20, 2012 Author Share Posted January 20, 2012 So if decoder fires one of the motors connected to it cannot fire any of 3 left immediately, not just the first one? Link to comment Share on other sites More sharing options...
David55 Posted January 20, 2012 Share Posted January 20, 2012 Wired in tandem means that wires from the track goes to the first decoder. You then lead from this decoder to the second and so on.I have found that the decoders will throw two sets of points before needing a recharge. This is however per decoder, so if like me with 6 decoders I can throw 12 sets of points simultaneously.In this respect I have alloted my points to decoders which best suit my layout.

trainzcal2001 Posted January 23, 2012 Share Posted January 23, 2012 I found One technique to save a space on my point decoder but throw 2 points at once.This is what i didI removed a SMALL section of rubber casing on the wires( on each wire) then solder the ends of the wires of a seperate point motor with the correct wires soldered onto the black metal gaps and what ever the first motors programmed for it throws both points at once witha satisfying thunk soundForgive me for misspellings Link to comment Share on other sites More sharing options...
